AT AcmEE'IvT' r03 rnonoemrns,

To all whom it may concern:

Be it known that I, EDWIN B. DoNALDs'oN, citizen of the United States ofAmerica, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Attachments forPhonographs, of which the following is a specifiment of t cation.

This invention relates to phonographs and like instruments in which acylindrical recordis applied to a cylinder.

An object of the invention is to provide means for imparting to therecord an initial movement or thrust to disengage the record from theoylinder'and project it beyond the I end of the cylinder in order thatthe operator may handle the same by applying his fin ers to theinternal.wall of the cylinder an obviate any damage to the said recordwhich might result from handling the exterior surface. t

'A further object of this invention is to provide a means for connectingthe record actuating device to the end gate of the ordinaryPhOIIOgTQJiIhS, in order to impart the movee said end gate to theactuating mechanism; thus releasing and actuating the record at a singleoperation.

A still further object of the invention is to provide an attachment ofthe character notedthat can be applied to phonographs now in common usewithout in any way changing their construction; the said attachx fullyset forth and described.

In describing the invention in detail, referenee will be had to theaccompanying drawin s, forming part of this speclfication n whic likecharacters denote correspond- In parts in the several views, in whichgure 1,'is a topplan view of a portion of a phonograph showing theinvention applied Specification of Letters Patent. 7 Application filedMarch 28. 1907- Siarial No. 366.074- I Patented Feb. 25, 1908.

rear thereof. Fig. 3, is a view in elevation of the end thereof. Fig. 4,is a rear elevation showing a modified construction. Fig. 5, illustratesanother modification. Fi 6, is a perspective view showing the detai s ofconstruction of the attachment illustrated in Figs. 1 and 2. Fig. 7, isa detail view of a further modification.

In these drawings A, denotes a base of a phonograph, B, a' cylinder ofordinary construction and C, the end gate of an ordinary phonograph.

The attachment consists of a standard D, having suitable bearing E, atits end to re- 'move a rod F, which is adapted to-slide in said bearing.The standard has a suitable base or foot G, which is clamped orotherwise secured to part of av phonograph. The rear end of the rod F,has two curved arms H, their armed surfaces conforming to the contour ofthe surface of the cylinder, and being approximately the thickness of arecord, although the proportion of the arms is an immaterial detail.

The outer end of the rod has a pivotally connected link I, extending toa oint nearly under the retaining lever. A J, is attached to theretaining lever by the hook j, embracing said retaining lever and saidhook terminates in an angular extension K, to which the outer end of thelink I, is pivoted. 7 I V In the modification shown in Fig. 4, apihonograph may be provided with a bracket or if desired, the rod whichusually forms a portion of the phonograph maybe utilized as a meansforsuspending the hanger Y, which hanger terminates in bearings y, inwhich the rod W, may slide. In this form the remainder of the structure,viz: the rod,

' record engaging arms, the link and the means for securing the outerend of the link to a hook which engages the end gate of the honographare the same as those heretofore described and need not, therefore, bereferred to, in detail.

In the modification shown in Fig. 5, the

bracket V, is the same as that shown in Figs. 1, and 2, except that itis shorter and 1s stationed under the record. In this form the rod T, isslidable in bearings of the bracket and the arms'S, embrace the cyhnderfrom the bottom, while the link R, has a thereto. Fig. 2, is a view inelevation of the I hooked extension Q, 1 embracing the end able thereinhaving on its ends the arms 3,

which are to contact with the record. This modification is designed foruse on-phonographs not having the end gate and tor the purpose ofpermitting the manipulation of the said rod the outer end thereof has aright angular extension 4 forming a thumb piece, which is engaged by thehand of the operator for reciprocating the rod in its bearings.

VVhattI' claim is: v

1. An attachment for phonographs consisting of a bar adapted toreciprocate, bearings therefor, curved. arms on the end of thebar'shaped to the contour of'a cylindrical.

record and adapted to abut the end of" the record, an end gate, andmeans for connecting the bar tothe end; gate to take movement therefrom.

2. In an attachment iol' phonographs, abar adapted to reciprocate Wlthrelationto the cylinder of a onograph, record engaging means carried ythe said bar and suitable means for connecting the bar to the end gateof a phonograph whereby the said bar takes movement from the lever.

3. In an attachment for phonograph's, bar adapted to reciprocate, meansfor supporting the bar with relation to the record of a phonograph,record engaging members v carried by the bar adapted to contact with theinner end of the said record, means for ('onnccting the bar to the endgate of a phonograph whereby the movement of the end gate iscommunicated to the bar.

4.31m attachment for phonographs, having a cylindrical record,consisting of a reciprocating member, a bearing therefor, curved arms onthe end of the reciprocating member adapted to conform to the contour ofthe record and contact the ends thereof, where- .by the endwise movementof the record is afforded. I

5. An attachment for phonographs having a cylindrical record, consistingof a reciprocating rod, 2. bearing for the rod, curved arms on .the rodada ted to lie back of the end of thei record, an means forreciprocating the ror In testimony whereof I afiix my signature in thepresence of two Witnesses, this 5th day of March, 1907 EDWIN B.DONALDSON.
